Solar camera power planning: start with the load
Last checked 23 October 2026
Before choosing a solar panel or battery for a pan-tilt-zoom camera, ask for a site-specific energy assessment. Give the designer your intended operating pattern and the periods when recording must remain available.
PVsyst describes stand-alone presizing as a rough estimate: it uses monthly solar input with panel orientation and horizon, desired autonomy and an acceptable loss-of-load level. It recommends a detailed simulation with real components after presizing. This is software-method guidance, not a camera performance promise. PVsyst stand-alone presizing documentation.
Prepare an energy brief
| Input to supply | Evidence to request |
|---|---|
| Site and season | Location, installation months, panel direction and tilt, and dated photos of shading across the day. |
| Operating pattern | Measured power for standby, recording, live viewing, night illumination and pan/tilt operation; expected time in each mode. |
| Availability target | The acceptable interruption level and the period to cover without useful charging. |
| Battery and charging arrangement | Usable energy at the proposed operating conditions, permitted charge/discharge conditions, controller compatibility and the proposed wiring layout. |
Compare the assumptions, then the sizes
- Ask the designer to show the daily energy budget and the month that governs sizing.
- Request the assumed losses, shading treatment and reserve, rather than accepting an unexplained capacity recommendation.
- Agree what the camera should do when energy is low: preserve recording, reduce viewing, alert the operator or stop.
- Define a sample trial with a written operating schedule and logged energy data before accepting a configuration.
Treat every proposed battery duration as conditional on that brief. No operating duration is established for a camera on this page.
